Full installed cost in Hamilton
What does a new furnace actually cost in Hamilton β equipment, labour, gas line work, venting, and permits all included? Get a realistic installed-price range before you talk to a single contractor.

Size & BTU Calculator
Right output for Hamilton’s -18Β°C winters
Furnace sizing errors are surprisingly common in Hamilton. Oversized units short-cycle and wear out faster; undersized ones run nonstop and still leave rooms cold. Find the correct BTU output for your home.

Recommendation Quiz
80% AFUE, 96% AFUE, or heat pump?
Standard efficiency, high efficiency, or cold-climate heat pump? The quiz considers your home’s age, current heating costs, budget, and Ontario rebate eligibility to recommend the right system.
π
Savings Calculator
How much could you save on gas?
Upgrading from an 80% AFUE furnace to a 96% AFUE model can save $300β$600/year on your Enbridge bill in Hamilton. See your specific annual savings and how fast the upgrade pays for itself.

Operating Cost Calculator
Monthly gas bill β Hamilton Enbridge rates
Calculate exactly what your furnace costs to run each month using current Enbridge natural gas commodity rates and your furnace’s AFUE efficiency rating. Real Hamilton numbers, not a national average.
π§
Repair or Replace Quiz
Make the right call on your furnace
A cracked heat exchanger is a replacement trigger. A failed igniter usually isn’t. The quiz works through your furnace’s age, repair history, and the specific problem to tell you which way the math points.

Troubleshooting Wizard
No heat? Diagnose it before you call
Many Hamilton “furnace not working” calls in January are a tripped high-limit switch, a clogged filter, or a thermostat issue. Work through the wizard first β you might solve it in five minutes without a service charge.

Troubleshooting Wizard
Diagnose it before you call
AC running but not cooling? Making a strange noise? A significant number of Hamilton emergency calls turn out to be simple fixes. Work through the diagnosis checklist before spending on a service visit.

AC Running Cost
Monthly electricity cost β Hamilton
Ontario’s Time-of-Use electricity rates mean when your AC runs matters almost as much as how long it runs. Calculate your real monthly cost using Hamilton Hydro / Alectra rates and your unit’s SEER2 rating.
π
AC Savings Calculator
Is upgrading worth it?
Your 12-year-old AC eats more electricity than you think. See the annual savings from switching to a modern SEER2 system, how long before it pays off, and which Ontario rebates shorten that timeline.
Built for Hamilton β Not a Generic National Calculator
Hamilton has its own electricity utility (Hamilton Hydro services parts of the city; Alectra covers other areas), its own summer design temperature (roughly 31Β°C), and its own contractor labour market. A calculator pulling data from Edmonton or Vancouver pricing gives you numbers that don’t reflect what Hamilton homeowners actually pay. Every tool on this page is built around local data β real quotes our team has done in Hamilton, Stoney Creek, Ancaster, Dundas, Waterdown, and surrounding areas since 2000.
The furnace calculators are in development and will launch before the 2025β26 heating season. They’ll cover furnace installation cost, sizing for Hamilton’s climate, gas savings, and the repair-vs-replace decision β the same depth we’ve built into the AC tools.
